Absolutely no thrills, but is perfect if you're looking for a bed to sleep in.
Room 302 looked exactly like the pictures. Small, but has the amenities you need. Bed, kettle, microwave, fridge, cupboard, TV, coffee cups, both an AC unit and fan.
Check in was easy, clear instructions. Don't arrive before check-in time however that will cause confusion.
Apartment is off the main road therefore no traffic noises. It is a big, busy city so there are noises still. Lots of random cleaning noises and racket in the mornings, but only an issue if you sleep past 9am. No real complaints.
The location is a small walk from centralwOrld, and Sukhumvit is a bit further on. I wouldn't say its on your doorstep, but if you're prepared to walk 20-30 mins it's all good. Only negative, it is far from the train/metro network, which you need to access other areas of the city - therefore you might need to use taxis.
Around the apartment are 7/11s and plenty of local food cafes and street food.
